Description

Goods with alarm system

The present invention relates to an article having an alarm system capable of detecting positional information in a dried article while ensuring safety, workability, and convenience, and detecting a danger related to life such as heat stroke and alerting.

It is important for an operator who performs work in a harsh environment to manage the body condition of the worker during work. For example, heat cramps or heat syncopathies, sometimes referred to as heat stroke, can put the worker's life at risk in a field involving dangerous work. Particularly, firefighters in firefighting activities, in addition to protective equipment such as fireproof clothing, are equipped with bombs and various equipment, carry them in a high temperature environment close to the flame, so heat is easily generated in the firefighting clothing, The risk of exposure is high.

On the other hand, the firefighters are more likely to engage in activity beyond their fitness limit in their sense of duty. Under such circumstances, it has been demanded that firefighters detect and warn that the risk of heat stroke is high.

As a countermeasure therefor, for example, Patent Document 1 proposes an ear-bud type. However, since it is an earplug type, there was a problem of hurting the hearing of the fire engineer. In addition, when it was applied to fire fighting activities, durability in harsh environments could not be said to be sufficient. Patent Document 2 proposes a method of sending information detected by a temperature sensor to an external module via communication means and determining whether there is a risk of heat stroke in the external module. However, this method has a problem that the alarm system does not operate when the fire engineer is in a place where communication can not be ensured inside the building or under the ground.

Further, in Patent Document 3, a system for detecting thermal stress in fire fighting activities has been proposed. However, this method has a problem that the alarm system is not operated when the head protection is detached, in addition to the fear that the activity of the fire engineer is disturbed due to the characteristic of measuring at the head.

Hereinafter, a sensor for detecting biometric information will be described as a temperature sensor for detecting the inside temperature of the protective clothing, but needless to say, it is not limited to the temperature sensor.

The protective clothing for the manager is a protective clothing provided with a heat-illness warning system. The thermal-illness warning system includes receiving means for receiving an alarm transmitted from a transmitting means of a worker (fire-fighting protective clothing for firemen), alarm means, And a control means for controlling said alarm means. The protective clothing in this regard is suitably used, for example, as a protective garment for a fire brigade's large armor (fire fighting garment).

For example, when fire brigade and fire brigade each use a protective clothing with such a heat-stroke alarm system, the risk of heat stroke including the means of self-estimation of position while securing safety, workability and convenience is alerting It is possible.

Hereinafter, a heat-related-alarm system comprising a position information sensor, a three-axis acceleration sensor, a gyro sensor or a geomagnetic sensor or a combination thereof, and means capable of autonomously estimating a position using a temperature sensor (See also the unapproved drawings as appropriate).

As shown in Fig. 1, the heat-illness warning system is structured such that it is stored in the inside and outside of each of the workers 1a, 1b, 1c (1) (hereinafter, simply referred to as "operator 1" The detection devices 2a, 2b, 2c (2)

 (Hereinafter, simply referred to as " abnormal detection device 2 " when not particularly distinguishing), a first alarm generating device 3, and a second alarm generating device 4 held by a manager 5 other than the worker 1 .

2, the abnormality detection device 2 includes a sensor (position sensor, three-axis acceleration sensor, gyro sensor, geomagnetic sensor, air pressure sensor and temperature sensor) 201, CPU (processing means) 202, wireless module 203, memory A storage means) 204, an RTC (Real Time Clock) 205, a button 206, and a battery 207.

The first alarm generating device 3 may include a buzzer (abnormality notifying means) 301 and a CPU (processing means) 302, and further may include a small light 303 and a small motor (abnormality notifying means)

The CPU 202 of the abnormality detection device 2 and the CPU 303 of the alarm generating device may be the same. A system in which a plurality of first alarm generators 3 are included in one abnormality detecting device 2 may be used. A plurality of first alarm generating devices 3 are included, and it is possible for the user to notice the alarm early.

A sensor (a position information sensor, a three-axis acceleration sensor, a gyro sensor, a geomagnetism sensor, an air pressure sensor and a temperature sensor) 201 is a means for autonomously estimating the intrusion information of the building and the position information in the building, (Sensor) for measuring the temperature. The data acquired by the sensor 201 will be referred to as " sensor data ".

The CPU 202 performs various arithmetic processing using the memory 204. The wireless module 203 is a means for performing wireless communication with an external device (the first alarm generator 3 or the second alarm generator 4). The memory 204 is, for example, a RAM (Random Access Memory), a ROM (Read Only Memory), a HDD (Hard Disk Drive), or the like.

The RTC 205 is means for timekeeping, and can be implemented by, for example, a dedicated chip, and can be operated by receiving power from the internal battery even when the battery is not operating. The battery 207 is a power supply means and can be realized by, for example, a battery.

The button 206 is an input means operated (pressed down) by the operator 1. The CPU 202 as the judging means for judging whether or not the information detected by the sensor 201 and the sensor 201 is equal to or larger than the threshold value or for judging the intrusion of the building or the position uncertainty is arranged in the same unit (abnormality detecting device 2) It is possible to detect and diagnose the risk of heat stroke and warn the operator 1 even in an environment where wireless communication can not be used.

Next, the first alarm generator 3 includes a CPU 302, a buzzer 301, and a battery 306 as shown in Fig. The buzzer 301 is an alarm means for generating a buzzer sound by an instruction from the CPU 302. The light 303 or the small motor 304 is an alarm means for generating light or vibration in response to an instruction from the CPU 302. [

In addition to the sound of the buzzer 301, an alarm by light or vibration is issued, so that the operator 1 can recognize the alarm more quickly and reliably. The wireless module 305 is a means for wirelessly communicating with the abnormality detection device 2 and the external device (second alarm generating device 4). The battery 306 is a power supply means and can be realized by, for example, a battery.

2, the second alarm generating device 4 includes a panel-type computer 401, a buzzer 402, a wireless module 403, a memory device 404, an input device 405, and a battery 406 as shown in Fig. The panel-type computer 401 is a computer in which a processing section 411 including a CPU and the like, a storage section 412 including a RAM ROM, an HDD, and the like, and a display section 413, which is a liquid crystal display with a touch panel, are integrally mounted. With the panel-type computer 401, the operator can perform an intuitive manual operation on the display section 413. [ The buzzer 402 is an alarm means for generating a buzzer sound by an instruction from the panel-type computer 401. The wireless module 403 is a means for wirelessly communicating with an external device (the first alarm generator 3). The memory device 404 is a removable storage medium, and is realized by, for example, a flash memory. The battery 406 is a power supply means and can be realized by, for example, a battery.

The antennas of the wireless modules 203, 305, and 403 may be formed integrally with the protective clothing using conductive fibers or the like. For example, when the antenna is formed on the outer surface of the protective clothing, even if the abnormality detecting device 2, the first alarm generating device 3, and the second alarm generating device 4 are installed in the protective clothing, wireless communication can be performed without being disturbed by the protective clothing have.

Therefore, a fabric bag having a high electromagnetic wave absorption rate may be used for the protective clothing. An antenna integrally provided in the protective clothing can be formed by a method of depositing or printing a conductive material on a protective cloth in addition to the conductive fiber, a method of attaching an antenna previously prepared on a flexible substrate such as a flexible substrate to a protective clothing.

Next, an example of data stored in the storage means 204 which is the abnormality detection device 2 will be described. As shown in Fig. 4, the data of the storage unit is composed of five columns and described from the left in order.

The " worker " indicates the identifier of the worker 1. The "determination period (second)" is a period (second) in which the abnormality detection apparatus 2 periodically collects the data by the temperature sensor 201 and stores it in the memory 204, (Seconds) for judging the abnormality of the battery. For example, there is 60 seconds as a long cycle, and 10 seconds as a short cycle. For example, the time at which sensor data is collected from time to time is the time measured by the RTC 205.

With respect to the "inside temperature (° C)", the "recording value" at the top indicates the temperature in the clothes of the operator 1 acquired by the sensor 201 at the time of the biometric information. The " warning level " at the bottom indicates a temperature which is the first threshold value, and is set at 38 (deg. C) in Fig. Further, the limit value of various pieces of biometric information may be an absolute value or a relative value.

When the relative value is a limit value, it is possible to cope with the individual difference of the worker 1 and the fluctuation of the body condition every day, and the risk of heat stroke can be surely detected at a faster stage. In addition, a relative limit value and an absolute limit value may be used together for one judgment item (for example, body temperature). The determination as to whether or not each item is abnormal may be made based on the amount of change of data as described above, or may be performed on the rate of change of data (amount of change per unit time).

Next, an example of a screen displayed on the display section 413 of the second alarm generating device 4 will be described. As shown in Fig. 5, the display section 413 displays information for specifying an operator on the leftmost column as an administrator screen, and on the right column, items such as time, temperature in clothes, and judgment are displayed.

Next, the processing flow of the heat stroke alarm system will be described. Although there may be a plurality of the abnormality detecting apparatuses 2 in actuality, the case will be described as one case in order to simplify the explanation. As shown in Fig. 3 (refer to other appropriate drawings), first, the abnormality detection device 2 measures the sensor data at normal time before the work by using the sensor 201 when the power is turned on by the worker 1 (step S1) And stores the sensor data in the memory 204 (step S2). Thereafter, the worker 1 starts work.

Next, the CPU 202 of the abnormality detection device 2, which is the determination means, determines whether or not the determination timing has arrived based on the determination cycle (Step S3), and proceeds to Step S4 when it comes (Yes).

In step S4, the CPU 202 of the abnormality detection device 2 collects the sensor data and stores it in the memory 204. [ It is also possible to check the voltage of the battery 207 and the communication state with the first alarm generator 3 or the second alarm generator 4.

Next, based on the sensor data collected in the immediately preceding step S4, the CPU of the abnormality detection device 2, which is the judgment means, judges whether or not it is equal to or higher than the alarm level (whether the "judgment" item is "abnormal" (Step S5). If the answer is Yes, the process proceeds to step S6, and if the answer is No, the process returns to step S3. In step S6, the CPU 202 of the anomaly detection device 2 notifies the first alarm generation device 3 of the alarm content (see Fig. 3).

The first alarm generating device 3 activates the alarm means when the alarm content is received from the abnormality detecting device 2. Concretely, for example, by sounding the buzzer 301, the operator 1 is notified of the effect. At this time, the small motor 304 may be operated to generate vibration. The operator 1 can immediately recognize the occurrence of an abnormality even in a working environment where the noise is large and the sound of the buzzer 301 is difficult to hear due to the vibration caused by the small motor 304. [

Thus, according to the heat-illness warning system of the present embodiment, the risk of the heat stroke of the worker 1 and the state of intrusion into the dried material are reliably detected in accordance with the abnormality detecting device 2, and in the first alarm generating device 3, And the vibrations caused by the small motor 304, it is possible to reliably cope with the physical abnormality of the worker 1. [

The operator has at least one of the abnormality detecting device 2 and the first alarm generating device 3. Or the CPU of the abnormality detection device 2 and the CPU of the first alarm generating device 3 are preferably the same, that is, even in a situation where wireless communication can not be performed between the first alarm generating device 3 and the second alarm generating device 4, 1 It is possible to reliably detect the abnormality of the body, and notify the operator 1 of the abnormality.

As described above, according to the present invention, it is possible to reliably detect a body abnormality such as a heat stroke of the worker, and to detect the abnormality of the worker by himself or herself due to sound by the buzzer 301, light by the light 303, vibration by the small- It is possible to reliably cope with the abnormality of the worker 1's body. That is, even when the first alarm generator 3 and the second alarm generator 4 can not communicate wirelessly, it is possible to reliably detect the abnormality of the body of the worker 1 and notify the operator of the abnormality.

Further, in addition to notifying the operator 1 of abnormality, the abnormality detection device 2 wirelessly transmits to the remote second alarm generating device 4 the above effect (alarm content, warning content) so that the manager 5 can notify the second alarm generating device 4 It is possible to grasp the abnormality from the display and appropriately take action.

It is also possible to calculate the limit value for judging the abnormality of each item on the basis of the biometric information (normal value) of the worker 1 when the power of the abnormality detection device 2 is turned on instead of the common value of all the workers 1, It is possible to reliably detect the danger of the risk in the earlier stage and to reduce the amount of misinformation.

In addition, the abnormality detection device 2 can reduce the consumption of the battery 207 by transmitting the radio signal only when it is determined that there is an abnormality in the body of the worker 1, other than periodic transmission of the sensor data. Further, for example, in addition to the in-clothing temperature sensor, the sensor for acquiring the biometric information of the worker 1,

A heart rate sensor, a temperature sensor, a humidity sensor, an acceleration sensor, a sweating sensor, a blood pressure sensor, etc., biometric information or ambient environment information, or a combination of two or more thereof. These sensors may not necessarily be integrated within the abnormality detection device 2, and may be configured so as to be able to send predetermined biometric information to the abnormality detection device 2.

Even if the operator 1 determines that the worker 1 is abnormal in the anomaly detection device 2 and then the operator 1 presses the button 206 within a predetermined time, the anomaly signal is not transmitted (canceled) to the second alarm generator 4 good. However, in the case where it is apparent that there is an abnormality in the body of the worker 1, such cancellation is not appropriate, so it is preferable to set such a cancellation only when the worker 1 can not be determined to have an abnormality .

The value of the warning level to be set is not limited to the present embodiment, but can be appropriately set by the manager 5 based on statistical data or the like. Alternatively, the threshold value may be set to either the warning level or the alarm level.

Although the embodiment has been described above with the heat stroke sickness alarm system as an example, the related alarm system is applicable not only to heat stroke sickness alarm but also to scenes in which various kinds of dangers are alarmed or to people. The protective equipment provided with the alarm system is not limited to the protective clothing, but may be a helmet, a glove, a boot, a watch, a headband, or the like.

In addition, the alarm system according to the present invention can be connected to a server or the like located far away from the network, and can accumulate and utilize information. 7 is a diagram showing a system in which the second alarm generating device 4 held by the manager 5 is connected to the server 8 installed at a remote place via the network 7 such as the wireless communication with the base station 6 and the Internet.

7, biometric information, positional information, etc. of the operators 1a and 1b are acquired by various sensors provided in the respective abnormality detection apparatuses 2 and transmitted to the server 8 through the second alarm generating apparatus 4 of the manager 5, Alternatively, the first alarm generating device 3 of the workers 1a and 1b may be a system that is connected to the server 8 through the wireless communication with the base station 6 and the network 7.

The server 8 regularly or periodically measures the biometric information such as body temperature, heart rate, blood pressure, and breath volume of the workers 1a and 1b from the sensors of the abnormality detection device 2, calculates an average value in daily life, A threshold value determined to be abnormal is determined for each worker, and it is possible to appropriately deal with each worker 1. [

Further, when the biometric information is acquired routinely or periodically by the server 8, the change in the body condition of the worker 1 becomes easy to be noticed. For example, when the warning system according to the present invention is applied to uniforms such as a bus or taxi driver who is responsible for many lives, it is possible to detect an abnormality of the driver early and take countermeasures. The normal biometric information of the worker 1 stored in the server 8 can be input not only from the sensor of the abnormality detection device 2 but also external information such as periodic examination and the like. The limit value of the biometric information may be determined.

When the biometric information and the positional information of the worker 1 are managed by the server 8, the server 8 installed in the fire station, for example, grasps the position and working environment of each fire brigade in operation, It is possible to contact firefighting bulletin manager five people from fire department whether there is firefighting team with abnormality of burden of firefighting bulletin can reduce burden of firefighting bulletin book.

In addition, it is possible to investigate and analyze the behavior trajectory of the worker 1 during work and the body condition at that time by accumulating position information (including altitude information) and biometric information data in the server 8. [ For example, firefighters, SDF, army, rescue team, police officers, security guards, construction and civil engineering. Workers at construction sites such as roads can conduct reviews to improve safety and efficiency in future activities, or they can be applied as materials for training and education.

In addition, the biometric information, the positional information, and the like of the operator 1 may be displayed in a field of view such as glasses or goggles of the principal or other person. In addition, a battery or the like serving as a power source for each sensor or sensor has a self-diagnosis function and can have a correction function for automatically diagnosing and confirming whether it normally operates based on a test signal on a daily basis or immediately before performing a task have.

When the result of the self-diagnosis is transmitted to the server 8 and accumulated, the data can be concentratedly managed and used as maintenance plan data. It is also possible to notify the wearer of the abnormality by the alarm generating device 3, the alarm generating device 4, or the like, and stop the use.

The specific configuration of the hardware or flow chart of the alarm system can be appropriately changed without departing from the object of the present invention.

Next, each component will be described. The temperature sensor for detecting the inner temperature of the protective clothing preferably has a measurement accuracy of 0.1 ° C. Thus, the risk of heat stroke can be detected with high accuracy. Thermocouples or Peltier devices can be used as sensors.

The temperature sensor is preferably disposed on the skin side surface of the interlayer or innermost layer of the multi-layer structure fabric. By arranging the temperature sensor near the living body, it is possible to detect the thermal environment which is a risk factor of heat stroke.

The means other than the temperature sensor is not necessarily disposed on the skin side surface of the multi-layer structure or in the innermost layer, but may be disposed outside the outermost layer. However, at that time, it is preferable that waterproof treatment is appropriately applied to such means.

The sensor or the warning means or the transmitting means or the receiving means may be a rectangular parallelepiped or a conical solid or may be formed in a flexible form. Examples of the flexible form include plate-like, fibrous, gel-like, and the like. By constituting a material having higher flexibility, it is possible to reduce the worker's activity limit.

As the article which gives such a temperature sensor or an alarm means or a transmitting means or a receiving means, clothes made of a multi-layer structure fabric are suitably used. The garments are always worn on the body during work, and besides being suitable for constant monitoring, unlike a helmet or earphone, it is difficult to hinder the work or movement of the worker. However, it goes without saying that this does not exclude the attachment to a helmet or an earphone.

By equipping these sensors or warning means or transmitting means or receiving means in a plurality of portions, there is a possibility that the overall weight of the equipment and the workability may be improved.

In addition, by making the fabric to have a multilayer structure, various functions which are difficult in the single-layer fabrication can be imparted to the garment at the same time. Examples of the functions include flame retardancy, heat resistance, water repellency, chemical permeability, abrasion resistance, and abrasion resistance.

Such a multilayer structure fabric is preferably, for example, those described in JP-A-2014-091307 and JP-A-2011-106069. That is, as follows.

The multi-layer structure fabric is a laminated fabric consisting of two or more layers of an outer layer and an inner layer. In the multi-layer fabric foil, it is preferable that the fiber material is highly flame retardant in order to protect the temperature sensor disposed on the skin side surface of the interlayer or the innermost layer of the multi-layer fabric.

For example, the limit oxygen index (LOI) of the fibers constituting the multilayer fabric is at least 21, preferably at least 24. The limiting oxygen index is the oxygen concentration (%) of the atmosphere necessary for continuing the combustion. When it is 21 or more, it means that self-extinguishing does not continue in the ordinary air, and high heat resistance can be exhibited. Here, the limit oxygen index (LOI) is a value measured by JIS L1091 (Method E).

As described above, by using the fiber having the limit oxygen index (LOI) 21 or more as the outermost layer, high heat resistance can be exhibited. Examples of the fiber include, for example, meta-aramid fiber, para-aramid fiber, polybenzimidazole fiber, polyimide fiber, polyamideimide fiber, polyetherimide fiber, polyarylate fiber, Oxazole fibers, nobloid fibers, poly crumb fibers, flame retardant acrylic fibers, flame retardant rayon fibers, flame retardant polyester fibers, ovoid cotton fibers, and flame retardant wool fibers.

In particular, meta-based aramid fibers such as poly (meta-phenylene isophthalamide) and the like, para-aramid fibers such as polyparaphenylene terephthalamide or fibers obtained by copolymerizing the third components with aramid fibers It is useful to use.

As an example of the polyparaphenylene terephthalamide copolymer, copolyparaphenylene 3,4'-oxydiphenylene terephthalamide is exemplified. However, a polyester fiber, a polyamide fiber, a nylon fiber, and an acrylic fiber may be used in combination as long as the flame retardancy is not impaired.

The fibers may be originally formed fibers or post-formed fibers. It is also possible to impart flame-retardant processing to the fabric immediately after the fabrication if necessary.

The aforementioned fibers may be long fibers or short fibers. Further, two or more kinds of the fibers may be mixed or blended.

In particular, in the present invention, it is preferable that the meta-based aramid fibers and the para-aramid fibers are used in the form of yarns in the form of filaments or mixed yarns. The yarn used may be a single fly or double flyer.

The blending ratio of the para-aramid fibers is preferably 5% by weight or more based on all the fibers constituting the fabric, but since the para-aramid fibers tend to cause fibrillation, the blending ratio is suppressed to 60% .

The fabric may be used in the form of a fabric, a knitted fabric, a nonwoven fabric, etc., but a fabric is particularly preferable. Further, as the fabric, any fabric structure such as plain weave, twill weave, runner weave is preferable. Further, two kinds of fibers may be used for fabrics and knitted fabrics and knitted.

The weight per unit area of the fabric used in the outermost layer is preferably 140 to 500 g / m 2, more preferably 160 to 400 g / m 2, and still more preferably 200 to 400 g / m 2 Is preferably used. When the weight per unit area is less than 140 g / m 2, sufficient heat resistance may not be obtained. On the other hand, when the weight per unit area exceeds 500 g / m 2, there is a fear that wearing comfort in the case of heat-

In the multi-layer structure fabric, the inner layer has a tensile modulus of 80 to 800 cN / dtex and a thermal conductivity of 6.0 W · m -1 · k -1 or less, preferably 5.0 W · m -1 · k -1 or less, It is also preferable that the fabric has a density of 3.0 g / cm 3 or less and has a transmittance of 10% or less for electromagnetic waves having a wavelength of 800 to 3000 nm and a weight per unit area of 60 to 500 g / m 2.

The tensile modulus of the fibers is preferably 80 to 800 cN / dtex (more preferably 80 to 500 cN / dtex, and further preferably 120 to 500 cN / dtex). When the tensile modulus of elasticity is less than 80 cN / dtex, fibers are elongated at some portions depending on the movement and attitude of the wearer in the case of using as a heat-shielding active clothing or the like, so that the fabric becomes thin and a sufficient heat shielding effect can not be obtained.

In addition, when the tensile modulus exceeds 800 cN / dtex, a so-called stretched fit may be given. There is a possibility of preventing this by using a yarn spun yarn, but it is preferable that the tensile elastic modulus is 800 cN / dtex or less in order to exhibit a sufficient effect.

In the multi-layer structure fabric, the weight per unit area of the fabric is preferably 60 to 500 g / m 2 (more preferably 80 to 400 g / m 2, and still more preferably 100 to 350 g / m 2). When the weight per unit area is less than 60 g / m 2, the permeation of electromagnetic waves may not be sufficiently prevented. On the other hand, if the weight per unit area is higher than 500 g / m 2, the tendency to collect heat becomes significant, which may hinder heat shrinkage and may hinder light weight.

The fibers constituting the multi-layer structure fabric are not particularly limited. In order to improve absorption and reflection of electromagnetic waves, it is also possible to knead a metal or carbon or the like and attach it to the surface.

As the fiber, a carbon fiber may be used. However, it is also possible to use a fiber such as aramid fiber, polybenzimidazole fiber, polyimide fiber, polyamideimide fiber, polyetherimide fiber, polyarylate fiber, polyparaphenylenebenzobisoxazole fiber (Hereinafter referred to as organic polymer fibers) composed of organic polymers such as polyvinyl chloride fibers, norbornene fibers, norbornene fibers, norbornene fibers, norbornene fibers, norbornene fibers, .

In multilayer structure fabrics, fine particles of carbon, gold, silver, copper, aluminum and the like can be contained in the organic polymer fibers or adhered to the surface of the organic polymer fibers due to the improvement of the electromagnetic wave absorptivity and the thermal conductivity. At this time, the carbon or the like may be contained in the organic polymer fiber as a pigment or a paint containing it, or may be imparted to the surface.

The content or deposition rate with respect to the total weight of the organic polymer fibers of these fine particles varies depending on the specific gravity of the fine particles, but is preferably 0.05 to 60 wt%, more preferably 0.05 to 40 wt%. In the case of carbon fine particles, the amount is preferably 0.05% by weight or more, more preferably 0.05 to 10% by weight, and still more preferably 0.05% by weight to less than 5% by weight. In the case of aluminum particles, the content is preferably 1% by weight or more, more preferably 1 to 20% by weight, and even more preferably 1 to 10% by weight.

The number average particle diameter of the fine particles is preferably 10 占 퐉 or less (more preferably 0.01 to 1 占 퐉).

If the carbon fiber or the metal fiber itself satisfies the above-mentioned requirements such as the LOI value and the thermal conductivity, the fine particles may be used without being kneaded. In particular, as the fibers constituting the inner layer, a fabric bag composed of preferably 50% by weight or more, more preferably 80% by weight or more, and even more preferably 100% by weight of carbon fiber or metal fiber is preferable.

Further, the thickness of each layer of the multi-layer structure fabric greatly affects the heat resistance. For example, as described in JP-A-2010-255124, it is preferable that the thickness of the outer layer and the thickness of the inner layer satisfy the following formula.

5.0 mm ≥ Thickness of heat insulation layer (mm) ≥ -29.6 Х (Thickness of outer layer (mm)) + 14.1 (mm)

By using a multi-layer structure fabric with high heat resistance, it is possible to protect the sensor, the warning means, the transmission means, and the reception means disposed on the skin side surface of the multilayer structure fabric or between the layers on the skin side of the innermost layer from the flames, It is possible.

In the multi-layer structure fabric, the normal time and the fabric type may change under the flame exposure. For example, it is believed that the fabric thickness increases with exposure to flame. As described above, it is possible to prevent the risk of heat stroke from being increased while the thin and pleasant fabric structure at the normal time, and at the time of flame exposure, the flame protection property is increased, thereby securing high safety against both heat stroke and flame.

It is also preferable that the heat resistance of the fabric for forming the protective clothing is measured by the method specified in ISO 9151, and the HTI24 is 13 seconds or more. Therefore, it is possible to protect the operator from the risk of flame, protect the sensor or the warning means, the transmitting means or the receiving means provided in the clothes from the flame and to normally express each function.

Further, the water repellency of the fabric made up of the protective clothing is preferably measured by the spraying method prescribed in JIS L1092, and is preferably third or higher. Thus, by protecting the temperature sensor provided in the protective clothing from water or liquid chemicals and preventing a short circuit or a short circuit,

Each function can be normally expressed. The multi-layer structure fabric can be treated with a fluorinated water repellent resin by a coating method, a spraying method, a dipping method, or the like, to provide a protective garment having high water resistance and chemical resistance. Water repellency may be expressed by adding a layer having high water resistance in the range satisfying flame retardancy and heat resistance.

In the multi-layer structure foil, it is preferable that the shrinkage ratio is 10% or less (more preferably 5% or less) in view of satisfying the international performance standard ISO11613-1999, which is applied to the fire protective suit for flame retardancy, heat resistance and resistance to washing.

Further, in the international performance standard ISO11613-1999, it is preferable not to ignite, to separate, to drop, and to not melt. As a result, it is possible to protect the temperature sensor, the alarm means, the transmitting means, and the receiving means, which are disposed inside the protective clothing, from the flames and reliably transmit the alarm information.

In the multi-layer fabric bag, it is also possible to arrange a moisture-permeable, waterproof film laminated and bonded to a fabric bag having an LOI value of 25 or more as an intermediate layer between the outer layer and the inner layer. Therefore, it is more preferable as a protective clothing for a firefighting team to carry out a fire fighting activity in which waterproofing and the like are performed because intrusion of water from the outside can be suppressed while keeping comfort as a fabric back structure.

The weight per unit area of the intermediate layer used is preferably in the range of 50 to 200 g / m 2. When the weight per unit area is less than 50 g / m 2, there is a concern that sufficient heat shielding performance can not be obtained. On the other hand, when the weight per unit area exceeds 200 g / m 2, .

This fabric is preferably laminated to a thin film made of polytetrafluoroethylene or the like having moisture permeability and waterproof property, thereby improving the moisture permeability and chemical resistance, promoting the evaporation of the sweat of the wearer, It is possible to reduce the stress.

The weight per unit area of the thin film laminated on the intermediate layer is preferably in the range of 10 to 50 g / m 2. Further, even in the case of laminating a thin film to the fabric of the intermediate layer, it is preferable that the weight per unit area of the fabric of the intermediate layer subjected to the processing is in the range of 50 to 200 g / m 2 mentioned above.

In addition, it is also possible to add the inner side of the inner layer, that is, the skin side lining layer, in consideration of practicality such as feel, wearability and durability. The weight per unit area of the fabric used in the lining layer is preferably in the range of 20 to 200 g / m 2.

The protective clothing may be formed by, for example, a fabric of outer layer, a fabric of inner layer, if necessary, a fabric of intermediate layer therebetween, and further, if necessary, And then sewing it in a known manner.

Further, in the laminated fabric of the present invention, the outer layer and the inner layer are stacked, a fastener is attached, these fabric is sewed, the fastener is removed, and the fabric is separated as necessary.

By combining the abnormality detecting device 2, the first alarm generating device 3, and the second alarm generating device 4 in the related protective clothing, a protective garment provided with a heat-illness alarm system can be obtained.

Here, it is preferable that the abnormality detecting device 2, the first alarm generating device 3, and the second alarm generating device 4 are disposed on the body front side of the protective clothing. In addition to not impeding the movement at the time of activity, it prevents the injury of the person and the breakage of the apparatus by arranging the body relatively easily in the case where the body suddenly falls or hits the wall.

Regarding the arrangement method, various methods can be applied as long as the method is attached to the protective clothing. For example, the pockets may be stored during suturing, or may be secured with straps, bands, face fasteners, fasteners, snap buttons, adhesive tapes, and brackets. In addition, they can be directly sealed or pasted.

At this time, it is preferable that the anomaly detection device 2 including the sensor is disposed on the skin side surface between the layers of the multi-layer structure fabric or the innermost layer. This is to accurately detect the temperature rise of the person who is the main cause of heat stroke.

According to the present invention, it is possible to precisely detect the state of the wearer of the protective equipment since it is possible to detect the state of intrusion into the dried material as well as the risk of life such as heat stroke, while ensuring safety, workability and convenience. Further, in the present invention, it is also preferable to add an algorithm such as a structure instruction and emergency service to reach the nearest member.
